Operating System not found

Operating System not found

Hi, I have a Sony Vaio VGN-C1Z/b and have done for the past 2 years. I have had no real problems until last night when I turned it on and after the VAIO logo appeared, the message "Operating system not found" followed.

When going into BIOS, I discovered that it is not recognizing my hard-drive. How do I fix this? Also, F10 recovery will not load.

Start off by removing the HDD and refitting it. It is just possible that the Connectors have got dirty and are no longer making a clean connection though if that was the case I would have expected bigger problems previously.

As for what to do from here you don't have much choice you can buy and have fitted a New HDD and Optical Drive and in the meantime contact Sony for a Recovery Disc for this system.

Or you can buy a new NB and use that. You may be able to recover your Data off the Old HDD but then again you will most likely not.

As for all NB users they should be using a Cool Pad like the one shown here

That do not Auto Detect the HDD's so when they are powered down and then turned back on as the HDD isn't seen there is no OS to be found.

Naturally it doesn't happen on the newer M'Boards that Auto Detect the HDD but what they do is once they loose the Date & Time Stamps the System doesn't load as the Files on the HDD are newer than the date that the BIOS claims it to be so the system hangs because Computer Logic tells the system that something is wrong here.
